摘　　要：针对辐射源目标测量误差和弹道修正门限对末修子弹命中精度的耦合影响,建立了末修子弹六自由度简化弹道模型,提出了基于蒙特-卡洛法的弹丸角偏差参数——偏角和方位角的优化方法,并通过仿真得到不同的修正门限和目标测量误差条件下的系统命中精度CEP曲线。考虑到目标测量允许误差越大越易于探测器的工程实现,给出了目标测量误差指标和对应的修正门限值,为系统研制提供了设计依据。In view of coupling influence of target-measurement error and correcting threshold on anti-radiation terminal course correction submunition system precision, the target-measurement model of radiation sourse was established on base of the six-degree rigid exterior ballistic trajectory model and the working principle. To solve this problem,a method of optimization of angular deviation parameter projectiles declination and azimuth simulation analysis optimization based on Monte-Carlo simulation method was put forward and the CEP curve under the conditions of different correction threshold and target measurement errors by simulation was obtained. Considering the allowable error of target-measurement under the system requirement, the study gives the measurement error and the corresponding threshold which provides a basis for system design.
